"She was rather calm when she made that call and she expressed that she needed police presence," said Jackson Police Chief Lindsey Horton.

After the Jackson Police Department got the initial call from Harrion, officers arrived at her house within eight minutes, authorities said. They knocked on the door, but got no answer, JPD officials said.

"While we did a good investigation, we obviously did not do one to the extent that we covered the entire property. We know that now, and I do think our officers could have done a better job," Horton said. "I think that our officers should have made contact with her. They made an attempt to knock on the door. They were not able to raise her and that was the extent of it."

JPD protocol is to make contact with the victim to make sure the homeowner is OK, Horton said.

About 1 p.m., Harrion's son found her body in the backyard of her Kingsroad Avenue home. The Hinds County coroner said Harrion had been beaten, strangled, her neck was broken and she had been shot in the face.

Horton said officers now believe that Harrion did not surprise a burglar, as was initially thought. He said there was no evidence to support a burglary because nothing was taken. There was evidence of a struggle, he said.

Evidence revealed that Harrion had a gun and fired once. Investigators have been checking area hospitals to see if anyone had been treated for a gunshot wound.

Neighbors reported seeing two men running from Harrion's home, which is a lead investigators are looking into. Officers returned to the scene Wednesday morning to gather additional evidence.

Anyone with information about the case is asked to call Crime Stoppers at 601-355-TIPS.
